AP EAMCET · PHYSICS · Capacitance
Eight drops of mercury of equal radii and possessing equal charge combine to form a big drop. If the capacity of each drop is ' C '. then capacity of the big drop is
- A 4 C
- B 2 C
- C 8 C
- D 16 C
Answer & Solution
Correct Answer
(B) 2 C
Step-by-step Solution
Detailed explanation
Volume of big drop \(=8 \times\) volume of small drop \(\Rightarrow \frac{4}{3} \pi R^3=8 \times \frac{4}{3} \pi r^2 \Rightarrow R=2 r\) \(\therefore \quad\) Capacity of big drop,…
